Log Context

Log “Cannot find an key [” + aggName + “] in [” + name + “]”classname  is InternalMultiBucketAggregation.java We extracted the following from Elasticsearch source code for those seeking an in-depth context :

if (bucket.getKeyAsString().equals(aggName.substring(1; aggName.length() - 1))) {
 return bucket.getProperty(name; path.subList(1; path.size()));
 }
 }
 // No key match; time to give up
 throw new InvalidAggregationPathException("Cannot find an key [" + aggName + "] in [" + name + "]");
 } 
 Object[] propertyArray = new Object[buckets.size()];
 for (int i = 0; i < buckets.size(); i++) {
 propertyArray[i] = buckets.get(i).getProperty(name; path);
